Designing Bird Free Sheds: A Humane Approach


The challenge of maintaining a bird-free environment within sheds has long been tackled using methods that, unfortunately, often result in harm to our feathered friends. Traditional approaches involve the use of spikes or sonar wave machines, which can be effective but may cause distress or harm to the birds. In a heartening move towards compassionate design, a recent project presented a unique solution that not only addressed the client's need for a bird-free structure but also prioritized the well-being of these winged creatures.

Client's Compassionate Approach:

The client, demonstrating a large-hearted approach, emphasized the importance of creating a bird-free shed without resorting to harmful methods. This presented a significant challenge as the conventional means of bird control often involved deterrence mechanisms that could cause harm to the birds.


Design Considerations:

To achieve the client's vision of a bird-free shed, the design team at KTSC took a thoughtful and innovative approach. Recognizing that birds typically roost on exposed flanges, the team decided to design rafters with box sections to eliminate these perching points. The absence of braces in the design further discouraged birds from finding comfortable spots within the structure.

Additionally, the purlins – horizontal roof beams – were designed in tubular sections, further reducing potential roosting spots. To enhance the effectiveness of this design, all purlins were positioned flush against the rafters, leaving no gaps for birds to settle in between. This meticulous detailing aimed to create a seamless, bird-resistant structure.

Box Sections for Rafters:

Birds often find a comfortable perch on the flanges of traditional rafters. To counter this, we designed the rafters in box sections, making it difficult for birds to find suitable perching spots.

Elimination of Braces:

Braces in traditional shed structures can provide additional surfaces for birds to rest. By eliminating unnecessary braces, we removed potential roosting spots, making the shed less attractive to birds.

Tubular Purlins:

Purlins, traditionally flat and inviting for birds, were redesigned in tubular sections. This not only made it less appealing for birds to land on but also added a sleek and modern aesthetic to the shed.

Flushed Purlin-Rafter Alignment:

One of the critical design features was ensuring that the purlins were flush with the rafters. This minimized the gaps between the purlins and rafters, leaving no room for birds to comfortably perch and reducing the overall attractiveness of the structure.

Successful Implementation:

With these considerations in mind, we successfully designed and implemented a bird-free shed structure that met the client's requirements. The project was completed within the specified timeframe, demonstrating the efficiency and effectiveness of our approach.


Creating a bird-free shed without resorting to harmful methods is not only possible but also an ethical choice that aligns with environmental consciousness. By incorporating thoughtful design elements, such as box sections for rafters and tubular purlins, sheds can be transformed into spaces that are uninviting to birds while maintaining functionality and aesthetics. If you have similar requirements for your project, consider reaching out to us at KTSC for innovative and humane shed design solutions. Together, we can build structures that coexist harmoniously with nature.
